船舶喷水推进介绍及设计方法

喷水推进是一种特殊的船舶推进型式，近二十年来才逐渐发展成熟。由于喷水推进具有噪声小、适应变工况能力强、抗空泡性能良好等优点，因而在高速、高性能船舶上得到越来越多的应用。本文分析了喷水推进的特点及工作原理，阐述了设计参数的计算、选择方法.本文最后总结了喷水推进器四种不同的设计流程。

Introduction and Design Method of Marine Water-jet Propulsion

Water-jet propulsion is a special marine propulsion type, has gradually developed and matured in the last twenty years. Water-jet propulsion has the advantages of low noise, strong adaptability to variable working conditions and high cavitation resistance, so has been used more and more in high-speed and high-performance ships. This paper analyses the characteristics and working principle of water-jet propulsion, and elaborates the calculation and selection method of design parameters. Finally, this paper summarizes four different design procedures of water-jet propeller.
